RC3216F7683CS Equivalent & Substitute Parts Reference

Part Overview

The RC3216F7683CS is a 768 kOhms ±1% 0.25W chip resistor manufactured by Samsung Electro-Mechanics in the 1206 (3216 Metric) package format. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 932 pieces available in inventory.

Equivalent and substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package format, dimensions, termination count). Substitutes enable design flexibility, supply chain alternatives, and component availability optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict parameter matching across electrical and mechanical domains:

Electrical Compatibility Criteria:

• Resistance value: 768 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Compatibility Criteria:

• Package format: 1206 (3216 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Composition: Thick Film (exact match required)

Compliance & Environmental Criteria:

• RoHS3 compliance (required for equivalent substitution)
• MSL 1 rating (required for equivalent substitution)
• REACH unaffected status (required for equivalent substitution)

All identified substitutes meet these criteria. Dimensional variations within supplier tolerances do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Product Status):

CR1206-FX-7683ELF (Bourns Inc.) and RC1206FR-07768KL (YAGEO) are direct equivalents with active product status. Both maintain full electrical and mechanical compatibility with RC3216F7683CS. Selection between these options depends on supply chain requirements, packaging format preference (Tape & Reel), and inventory availability. Bourns CR1206-FX-7683ELF offers the highest inventory level (26066 pcs).

Secondary Substitute (Automotive-Qualified, Obsolescence Status):

ERJ-8ENF7683V (Panasonic Electronic Components) meets all electrical and mechanical specifications and includes AEC-Q200 automotive qualification. However, this part carries "Not For New Designs" status, indicating product phase-out. This substitute is suitable for legacy system maintenance, repair, and rework applications only. New design implementations should prioritize active-status alternatives.

Compliance Verification:

All identified substitutes maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and environmental compatibility with the original RC3216F7683CS specification.

Frequently Asked Questions (FAQ)

Q: Can CR1206-FX-7683ELF replace RC3216F7683CS in existing designs?

A: Yes. CR1206-FX-7683ELF is a direct electrical and mechanical equivalent. Both components share identical resistance (768 kOhms), tolerance (±1%), power rating (0.25W), package format (1206), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). Compliance certifications (ROHS3, MSL 1) are identical.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Tape & Reel (TR) packaging is standard for automated assembly processes and high-volume production. Bulk packaging is typical for manual assembly or lower-volume applications. Electrical and mechanical specifications remain identical regardless of packaging format. Component selection should align with assembly process requirements.

Q: Why is ERJ-8ENF7683V marked "Not For New Designs"?

A: "Not For New Designs" indicates the manufacturer has discontinued active development and is phasing out this product line. Existing inventory remains available for support and maintenance applications. New circuit designs should specify active-status alternatives (CR1206-FX-7683ELF or RC1206FR-07768KL) to ensure long-term supply continuity.

Q: Are dimensional variations between substitutes significant?

A: Dimensional variations (length 0.122" to 0.126", height 0.026" to 0.030") fall within standard supplier tolerances for 1206 package format. These variations do not affect PCB layout compatibility, reflow soldering, or functional performance. All substitutes are mechanically interchangeable on standard 1206 footprints.

Q: Does AEC-Q200 qualification on ERJ-8ENF7683V provide additional benefits?

A: AEC-Q200 qualification indicates automotive-grade reliability testing and environmental stress screening. This certification is beneficial for automotive and high-reliability applications. However, for general industrial and consumer applications, standard ROHS3-compliant alternatives (Bourns or YAGEO) provide equivalent performance at potentially lower cost.

Q: Can these substitutes be mixed in the same production batch?

A: Yes. All identified substitutes meet identical electrical specifications, tolerance, and compliance requirements. Mixed sourcing is acceptable from a functional and regulatory perspective. However, manufacturing and quality documentation should clearly identify component sources for traceability and audit purposes.
